Correct.  This is the historical way rsync has worked, and I haven't
changed it -- at least, not yet.  I did make it possible to list files
from a local transfer, but you need to still include a destination along
with the --list-only option.  I like your idea of having rsync not fail
if the destination directory is missing when --list-only was specified.

When parsing the output of rsync, it is always better to use the
--log-format option with a prefix (something like %i or %t) to make
parsing the output more accurate than parsing the verbose messages.

I think the --list-only lines are unique enough that they can be
reliably differentiated from the rest of the output by a script.

The CVS version of rsync outputs non-printable parts of a filename using
octal (e.g. \012) escapes plus "\\" for backslash, so your script can
get the full name of each file without needing them to be '\0' separated
(it would just need to first change "\NNN" sequences back into a single
char, and then change any "\\" sequences into a single backslash).
